Thread guide for shoe upper lacing machines

THREAD GUIDE FOR SHOE UPPER LACING MACHINES Filed March 21, 1933 The tube of the twist resisting device is bent into circular form through at least part of a complete turn, and into engagement with itself, so that the entrance to the device is disposed at an angle to the exit. The tubular part of the device is connected to the guide 28 by an integral threaded sleeve 32 at the exit end of the device which is screwed into a'threaded portion of the guide 28 concentric with the passage through the guide. The device may be secured at any angle by a lock nut 34 provided on the threaded sleeve 32.

To permit the cord to be readily engaged in the twist resisting device the curved portion thereof is slotted at 36 along the outer wall of the curved portion so that the cord may be passed through the entrance end of the tube 30 and through the adjacent end of the slot 36. The end of the cord may then be passed through the slot 36 at the end nearest the exit sleeve 32, and through the sleeve and guide 28. When the end of the cord extending through the guide 28 is drawn further into the machine, the length of cord extending between the two ends of the slot 36 will automatically pass through the slot, displacement of the cord being prevented so long as the slightest tension on the cord is present. Preferably the engaging portions of the tube are joined together by soldering at 38.

The nature and scope of the invention having been indicated, and a particular machine in which the invention may be embodied having been described, what is claimed is:

1. A'lacing machine having, in combination, lace inserting and knot tying mechanism, means for applying cord to the lace inserting mechanism including a reciprocating. eye-pointed needle through the eye of which the cord passes, a guide for the cord between the needle and the cord supply, and twist resisting means having a passage, the entrance of which is disposed at an angle to the exit for preventing twist of the cord produced as it moves through the needle eye from kinking the cord entering the guide.

2. A lacing machine having, in combination,

lace inserting and knot tying mechanism, means for applying cord to the lace inserting mechanism including a reciprocating eye-pointed needle through the eye of which the cord passes,

a guide for the cord between the needle and the cord supply, and a curved tubular member bent into circular form back upon itself and connected to the guide for preventing twist of the cord produced as its moves" through the needle eye from kinking the cord entering the the outside of the bend to facilitate threading,

4. A lacing machine having, in combination, mechanism for forming and inserting a cord lacing through the eyelets of ashoe upper, and

a twist resisting cord guide through which the cord passes to said mechanism comprising a curved tubular member bent into-circular form and provided with a slot in'the bent portion in the outer wall thereof tofacilitate threading. 5

5. A lacing machine having, in combination,

mechanism for forming and inserting a cord lacing through the eyelets of a shoe upper, and

a twist resisting cord guide through which the cord passes to said, mechanism comprising a curved tubular member bent into circular form back into engagement with'itself and provided with a slot in the bent portion in the outer wall thereof to facilitate threading, and means for securing the engaging, parts of the-member to gether. i
